KNITTED FABRIC.

To all whom it may concern Be it known that I, FRANK CLEWLEY, a citizenof the United States, residing at Philadelphia, county of Philadelphia,and State of Pennsylvania, have invented a new and useful Improvement inKnitted Fabric, of which the following is a full, clear, and

exact description, reference being had to the accompanying drawings,which form a part of this specification.

The object of my invention is to provide a new and improved fabricespecially adapted for towels, wash cloths and other similar goods whichare frequently soiled and wetted and which it is important, from asanitary standpoint, should be such open mesh as to be capable of beingquickly and thoroughly dried. In a atent issued to me February 16th,1904, No. 52,033, a fabric of this character is set forth in whichchains of knitted loops, each chain composed ofa single weft thread, areunited by warp or filling threads alternately deflected to the right andleft. This fabric meets all sanitary requirements but when applied tocertain goods it does not possess the strength in the line of the weftthat it is desirable for it to have.

The object of the resent invention is to provide a knitted fa ricposessing a maximum of strength on the line of the weft.

The invention consists of a fabric having chains of knitted loops, andfilling threads alternately deflected to the right and left, as in saidpatent, but in which each chain of loops is formed by means of twoseparate weft threads forming alternate loops of the chain, and consistsalso of a fabric wherein the filling threads are interlaced with theweft threads in a particular manner that will be clearly apparent fromthe following description in. connection with the accompanying drawings,which illustrate a referred embodiment of my invention an in whichFigure 1 is an enlarged face view, and

Specification of Letters Patent.

Patented May 11, 1915.

Application filed A ugust a4, 1914. Serial No. aaaaas.

d and e is the same as that of the weft threads, but they arealternately deflected to the right or the left either between adjacentchains or across two or more adjacent spaces between chains; each ofsaid filling threads extending, in its passage through each loop,between two weft threads at and b of a pair. Starting with either weftthread of any one of the chains (say the weft thread a at the secondloop from the top of chain as), it will be observed that it extends downand through the third loop, formed by thread I) thence up and throughthe first loop, formed by thread I); thence down to complete the secondloop and again through the third loop, and continues down through thefifth loop, formed by thread 6; thence up and again through the thirdloop; thence down to complete the fourth loop: and so on. Starting withthe weft thread 6 at the third loop of the same chain w, it extends downand through the fourth loop, formed by thread a; thence up and throughthe second loop, formed by thread a; thence down to complete the thirdloop and again through the fourth loop, and continues down through thesixth loop, formed by thread a; thence up and again through the fourthloop; thence down to complete the fifth loop: and so on. Thus each weftthread extends alternat'ely up the length of one loop and down thelength of three loops and in its passage up and down extends thricethrough each loo formed by the other weft thread.

ach filling thread extends, in its passage through a loop, back of twosections of one weft thread and in front of one section of the same weftthread and one section of the other weft thread. If the filling thread,in its extension in one direction across the fabric, after passingthrough one loop, does not extend beyond the corresponding given chain,it is deflected, in the opposite direction, through the loop below itand thence across to the next chain and through the loop thereofcorresponding to the last named loop of the first chain. If the fillingthread, in its extension across the fabric, passes across a plurality ofsuccessive spaces, it extends successively through corresponding loopsof successive chains, and in its return in the oppositr direction, isdeflected first through the neat lower loop of the last chain.

Thus starting with the filling thread a to the left of the first loop ofchain 2:, it will be observed that it extends to the right through thefirst loop of chain a; and the first loop of chain 1 thence to the leftthrou h the second loop of chain 3 and the secon loop of chain to;thence to the right through the third loop of chain a: and the thirdloop of chain y; thence to the left through the fourth loop of chain 3and the corresponding-loops of chains 22. w and o, thence to the rightthrough the fifth loops of chains '0, w, a: and 3}; thence to the leftthrough the sixth loops of chains y, 0:, w and o, and thence back andforth through corresponding loops of chains 11 and w as above described.7

In the particular fabricshown in the drawings, the chains are dividedinto sets of four, while the filling threads are divided into sets ofthree (0, d and e). In those sections of the fabric in whicheach-filling thread extends across only a single space between chains,two adjacent sets of chains are unconnected, forming an open space. Thusan open space is formed between chain a: of one set of chains and chain10 of an adjacent set of chains. In those sections of the fabric inwhich a filling thread iscarried across a lurality of spaces betweenchains, two of t e three threads are carried across the space betweenadjacent sets of chains, thus closing the space between the sets ofchains.

The method of operating the needles whereby the above fabric will beformed will be apparent to one skilled in the art, and as such operationforms no part of the invention, the same is not described.

While I have differentiated the weft threads 0. from the weft threads I)by section-linin the one and not the other, it will be 111111 erstoodtilliat this is donililnerely to assist t e eye in 'stinglnshin' g e twothreads in the drawings, it being understood that these threads aresimilar one to the other and interlace with each other and with thefilling threads in precisel the same way. Also the two filling th 0, dand e are of like character and are given difierent reference lettersbecause, in the fabric shown, three of such threads areemsloyed in eachset of chains to form a close block separating two open spaces.

It will be understood that the number of chains and the number ofthreads in each closed block and the number of chains spanned by thefilling threads may be varied without departing from the invention.

While I have called the lo 'tudinally extending looped threads weft andthe uniting cross threads warp or filling threads, they may be notimproperly otherwise designated, as, for example, the looped thread maybe termed warp threads and the other threads weft threads.

Having now fully described my invention, what I claim and desire toprotect by Letters Patent is:

1. A knitted fabric comprisin a weft formed of a number of pairs 0threads forming chains, each pair of threads ex-,

tending along only a single chain and each thread of a pair formingloops interlaced with the 100 s of the other thread, and a warp formedof filling threads extending back and forth between and interlaced withthe chains.

3. A knitted fabric comprising a weft formed of a number of pairs ofthreads forming chains, each pair of threads extending along only asingle chain, each thread of a pair extending successively forward,backward and forward to form a loop engaging loops of the other threadrespectively in front and back of the first loop and thence extendingsuccessively forward,backward and forward to form a loop beyond andinterlaced with said forward loop of the second thread, and so on,whereby a chain is formed composed of alternating loops, and a warpformed of filling threads extending between and interlaced with thechains.

4. A knitted fabric comprising a weft formed of a number of pairs ofthreads, the two threads of each pair forming alternate loops of acontinuous chain of loops, each thread in the formation of a completeloop extending through one of the adjacent loops formed by the otherthread thence through the other ad'acent loop formed by the last namedthrea and thence through the first adjacent loop to the next loop formedby the first thread, and a warp formed of filling threads extending backand forth between and interlaced with the chains.

5. A knitted fabric comprising a weft formed of a number of pairs ofthreads, each thread of a pair being interlaced with the other thread ofthe pair to form a continuous chain of loops, and a warp formed offilling threads deflected back and forth between the chains andextending, at each point of interlace with a chain, between the two weftthreads of a pair.
